CHECK-ROWER FOR CORN-PLANTERS.

SPECIPTCATION forming part of Letters Patent liq 295,883, dated March 25, 1884:.

Application filedNovember 5, 18 3. (X model.)

To all whom it may concern:

Be it known that I, JOHN P. Moos, of Lincoln, in the county of Logan, and in the State of Illinois, have invented certain new and useful Improvements in Check-Rowers for Corn- Planters; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, inwhich Figure 1 is a plan view of the upper side of my apparatus separate from the corn-planter. Fig. 2 is alike View of the lower side of the same. Figs. 3 and 4 are respectively front and rear elevations of said apparatus. Fig. 5

is a perspective view of my vibrating cam.

separate from the other mechanism. Figs. 6

. and 7 arerespectively front and rear elevations of the same, and Fig. 8 is a side elevation of said cam. I

Letters of like name and kind refer to like parts in each of the figures.

The object of my invention is to simplify the construction, to lessen the expense, and to increase the accuracy of operation of cornplanters of the classin which the seed-dropping mechanism is actuated bya knotted line stretched across a field and caused to engage with and pass through the machine as the same travels to and fro and to this end said invention consists, principally, in the construction of the cam used for. converting. the constant movement in one direction of the check-row line into a reciprocating motion in opposite directions of the dropping mechanism, substantially as and for the purpose hereinafter specified.

It consists, further, in the construction of the check-row-lilie-operating mechanism and its combination with the dropping mechanism, substantially as and for the purpose hereinafter shown. I I

It consists, finally, in the means employed for holding the operating mechanism in place at each limit of its motion, substantially as and for the purpose hereinafter set forth.

In the annexed drawings, A represents a bar, which has such length as to cause it to extend across the entire machine, and at each end is provided with a short crossbar, B, that is secured thereto in a line with the draft or at a right angle to said bar A.

Secured to each end of each cross-bar B is aframe, O, which extends upward and slightly outward or inward, and furnishes a pivotal bearing for a grooved roller, D. The upper part,.the lower of which, in plan view, has

the form of an arc of a circle at its rear side, with a bar, e, extending from each side of its center forward in nearly a radial line and uniting with the other bar 6 in a curve at its front end. The upper section of said cam is shaped like said. lower section, except that there is an openspace between the rear ends of its bars (3 and a small opening between the front ends of the same. Said sections are united by posts 6 at the outer corners of their rear curved sides, as seen in Figs. 6,7, and 8. The space vertically between the corresponding bars 6 of each section is slightly greater than the diameter of the check-row .line F, while between the rear ends of saidbars and the adjacent post 6 the space is enlarged and has such size and shape as to admit of the ready passage of the balls or knots f of said line. The outer faces of each pair of said bars e are beveled toward each other, so as to produce a concave groove, along which said balls f may slide, and at the rear ends of said bars said groove has a slight horizontal curve toward the contiguous post 0, the object of which is to form a pocket, 6, at such point which will cause said ball to engage with said cam when it reaches such point. Thecams E are capable of oscillation in each direction a distance equal to about one-eighth of a revolution, andif attached to a machine and caused to move forward with the line F passing sides of the pair of bars 6, which are turned Ioo toward the front until it reaches the pocket 6, when it engages with the same and turns that side of said cam in the same direction to the limit of its motion. At the instant when the cam Ehas reached the limit of its motion in the direction in which it is being moved by the line F the change in the angle of the pocket e causes the ball f to be released therefromand to pass rearward from out of said cam, while by the change in the position of the latter the opposite side is presented to the next succeeding ball, which performs pre cisely the same operation and returns said cam to its first position, each ball thus operating to turn said cam from the point where it was left by the preceding ball to the opposite limit of its motion.

As shown in the drawings, the pockets 0* are so situated with reference to the pivotal point of the cam that the balls on the line will strike against the rear wall of the pockets before the tension of the line or cord can tend to turn the cam. In other words, as the balls pass rearward along the sides of the cam the tension of the cord acts on the am to keep it from turning until the balls strike the rear walls of the pockets. The cam will then be quickly and positively turned by the direct pull of the cord.

Nopawls or similar devices need be used with my construction to prevent turning of the cam by the action of the tension of the line, as heretofore. v

The movements of the cams E are eommu- 'nicated to the dropping mechanism by the following means, viz: Resting within suitable bearings, G, at the front side of the bar A is a rack-bar, H, which is capable of longitudinal motion within its bearings, and is ,connected with the lower side, near the front end of said cam E, by means of a red, I, that is pivoted to and extends between said parts. J ournaled within a suitable frame, K, at the lower side of the bar A is a shaft, L, which, near oneend, is provided with a segmental pinion, Z, that meshes with the toothed lower face, h, of the rack-bar H, and converts the longitudinally-reciprocating movements of the latter into a semi-rotary movement of said shaft.

The rear end of said shaft L is provided with a crank, Z, which is suitably connected with and actuates the dropping slides of the machine, the arrangement being such that each movement of a cam, E, causes a half-revolution of said shaft L and a complete movement of the dropping slides.

In order that the mechanism may be held in place at the end of each movement, and not be liable to be accidentally moved therefrom by the jolting of the machine, a lever, M, provided with a weighted upper portion, m, is pivoted at its lower forked end upon the bar A, and from a point above its pivotal bearing is connected with the rack-bar H by means of a rod, N, that extends between and is pivoted to each of the same. \Vhen, now, the rack-bar H reaches the limit of motion in either direction, the weight of the lever M,

pressing in the same directiomholds said bar' firmly in place without interfering with its freedom of motion from the action of the operating line.

Having thus fully set forth the nature and merits of myinvention, what I claim as new 1S- 1. The pivoted vibrating cam E, composed of an upper and a lower section, between which is a space for the check-row line, and provided at each side with guide-bars e, pocket 0" at the rear of the cam, and post 6, con necting the rear ends of the bars, and situated outside of and opposite the pocket, in combination with the check-row line F, provided with balls substantially as shown and described.

2. In combination with the pivoted vibrating cams E, the rack-bar H h, connections I, shaft L,.pini'on Z, crank Z, and reciprocating corn-dropping mechanism, substantially as and for the purpose set forth.

3. The rack-bar H, reciprocated through suitable connecting mechanism by the vibrating cam, in combination with the shaft L, carrying pinion Z and crank Z, the lever M, provided with weighted portion m, and the rod n, connected with the rack-bar H, substantially as and for the purpose described.

Intestimony that I claim the foregoing I have hereunto set my hand this 3d day of April, 1883.-
